IPC: G08G1/16
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To enhance the safety of vehicle traveling by detecting position by utilizing radio waves and also arranging plural lane markers to be indices for position detection in the width direction of a lane. SOLUTION: Plural electric wave type lane markers 1 to 3 are serially arranged on respective center lines of each lane and on both sides of the width direction of the center lines.

Title: Permanent-magnet rotor
Inventor: SOMA YUSUKE
IPC: H02K1/27
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To obtain a permanent-magnet rotor which can prevent a drop in reliability and performance by a method wherein an elastically deformable coupling part is formed in a position facing the edge of every ring-shaped permanent magnet in the outer circumferential part, its inner circumferential part is fixed and bonded to a rotor shaft and its outer circumferential part is fixed and bonded to the edge of the permanent magnet via the coupling part. SOLUTION: One pair of ring-shaped magnet fixation plates 3 are arranged so as to come into contact with the step part 1a of a rotor shaft 1 and with both edges of every permanent magnet 2, and protrusion-shaped coupling parts 3a in which a very small crack is provided so as not to be fractured are formed in positions which face the edge of every permanent magnet 2 in the outer circumferential part. Then, at both magnet fixation plates 3, their inner circumferential parts are fixed and bonded to the edge of the step part 1a by a welding operation, and their outer circumferential parts are fixed and bonded to the edge of every permanent magnet 2 by, e.g. a laser welding operation via the coupling parts 3a.  Consequently, since the coupling parts 3a are deformed elastically in the axial direction and the circumferential direction so as to absorb a difference in an expansion and contraction amount, the life of a rotor becomes long, and the reliability of the rotor can be enhanced.

IPC: F16D43/00
Filed: 1980-10-17
Abstract: PURPOSE: To prevent a change of torque or the like in the output shaft of a piston engine from being transmitted to a driving device, by converting the change of torque in the output shaft to an induction current in a change detector device, decreasing an excitation current of an electromagnetic clutch and causing a slip in the electromagnetic clutch.  
     CONSTITUTION: When a change of torque of fluctuation of rotary speed is transmitted from an engine output shaft 1 to a torque converter output shaft 2, movement is circumferentially caused between a clutch disc 6 and clutch boss 10 to move an arm 11. This movement generates an induction current between a magnet 12 of the arm 11 and coils 14. This induction current is guided to a rectifier circuit 17 through a slip ring 15 and bush 16, rectified, amplified, corrected and controlled by a computer 18, then caused to flow reversely to the excitation current in an electromagnetic clutch coil 9, thus the excitation current is decreased, Accordingly, a slip is produced in the clutch, and the change in the output shaft is not transmitted to a driving line, thus the driving line can be smoothly operated.

Title: Floating filter material and filter apparatus using the same
Inventor: TSUDA TOSHIO
IPC: B01D39/04
Filed: 1995-06-12
Abstract: PURPOSE: To sufficiently develop the capacity of submerged filteration by using a floating filter material having a compression ratio of a specific value when the filter bed in a filter apparatus is compressed by the differential pressure accompanied by the elapse of filtering treatment. CONSTITUTION: A floating filter material has compression properties such that pressure loss is generated with the elapse of a treatment time when the filter material is arranged in water or treated water and the height of the filter material bed is compressed within a range of 5/100-100/1000per the differential pressure rise of the filter material bed of 1m water column. As the floating filter material, a porous substance obtained by foaming polystyrene, polyethylene or polypropylene having specific gravity less than that of water is usually used because the surface area of the filter material is increased.  Since the filter material is compressed properly by the rise of differential pressure with the elapse of a filtering time, a hardly filterable suspended substance can be collected without passing through the gaps of the filter material and the collection rate of the suspended substance per the unit volume of the filter material is kept high for a long time and the number of times of the washing of the filter material per a unit time is reduced and the drain amt. of washing water is reduced.

Title: Method for predicting thunder
Inventor: SONOI YASUO
IPC: G01W1/16
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To improve the predicting accuracy of a thunder predicting method by discriminating hail and ice crystals from each other in a thunder cloud by using a prescribed threshold based on the reflection factor of a double polarized wave radar to horizontally polarized waves and the difference between the reflection factors of the radar to horizontally and vertically polarized waves. SOLUTION: It is confirmed that a hail zone grows in an area where ice crystals already exist in a thunder cloud and lightning occurs when the two kinds of participation particles come into contact with each other. A double polarized wave radar used for observing lightning phenomena radiates horizontally and vertically polarized waves having a beam width of 1.8 deg. from, for example, a rear feed type circular parabolic antenna having a diameter of 2m at a frequency of 5,280MHz and output of 75kW. Hail and ice crystals are discrintinated form each other based on the value of the reflection factor ZR of the radar to the horizontally polarized waves and the difference ZDR between the reflection factor values of the radar to the horizontally and vertically polarized waves.  Such a threshold that becomes ZR>=30dBZ and |ZDR|<=0.4 dB is used for hail and such a threshold that becomes ZR30dB and ZDB>=1.5dB is used for ice crystals. It is predicted that the possibility of occurring thunder becomes higher when the echo intensity to hail exceeds ZR>40dBZ.
